Kalshi is a US-based, federally regulated exchange where people trade contracts on the outcomes of real-world events, from interest-rate decisions to elections, weather, and sports. It operates as a designated contract market (DCM) under the Commodity Futures Trading Commission (CFTC), the same federal agency that oversees commodity futures. Each Kalshi market poses a clear yes-or-no question, and traders buy contracts that settle at either $1.00 (correct) or $0.00 (incorrect). Founded in 2018 and open to the public since 2021, Kalshi is legal for US residents and available on the web plus iOS and Android apps.

Kalshi Meaning: What the Platform Actually Is
The word “Kalshi” is the company name, not a financial term, so “kalshi meaning” usually points to the same question as “what is Kalshi.” At its core, Kalshi is a prediction market. A prediction market is a venue where the price of a contract reflects the crowd’s collective estimate of how likely an event is to happen. If a contract on “Will the Federal Reserve cut rates at its next meeting?” trades at 62 cents, the market is effectively pricing that outcome at roughly a 62 percent chance.
Kalshi differs from a casual betting site in one important way: it is a regulated financial exchange. The CFTC designated Kalshi as a contract market in November 2020, and the platform opened to the public in July 2021. That regulatory status means Kalshi lists standardized contracts, publishes rules for how each one settles, holds customer funds in segregated accounts, and reports to a federal regulator. It is the first company to receive this specific approval for trading directly on the outcomes of events.
The company was started by Tarek Mansour and Luana Lopes Lara, who met as students at MIT and built Kalshi in San Francisco. Their goal was to turn questions about the future into tradable, regulated instruments so that anyone could act on a view about an upcoming event the same way a trader acts on a view about a stock or a commodity.
How Does Kalshi Work?
Every Kalshi market is built around a single question with a defined resolution. Take a market such as “Will the high temperature in New York City exceed 90 degrees on a given day?” Traders can buy “Yes” contracts or “No” contracts. Contract prices move between 1 cent and 99 cents, and they always add up to roughly a dollar across the two sides. When the event resolves, the winning side is worth exactly $1.00 per contract and the losing side is worth $0.00.
Here is the mechanic that trips up most newcomers. You do not have to hold a contract until it settles. Prices move constantly as new information arrives, so you can buy a “Yes” contract at 40 cents and sell it at 55 cents before the event even happens, locking in the difference. This makes Kalshi feel closer to trading a stock than to placing a wager that is frozen until a game ends.
A concrete example makes it clearer. Suppose a market asks whether a named inflation reading will come in above a set level, and “Yes” is trading at 30 cents. You believe the number will beat expectations, so you buy 100 “Yes” contracts for $30 total, plus a small fee. If the reading confirms your view and the market resolves “Yes,” each contract pays $1.00 and your 100 contracts are worth $100, a gain of $70 before fees. If it resolves “No,” the contracts expire worthless and you lose the $30 you put in. Alternatively, if fresh data pushes the price to 45 cents an hour before settlement, you could sell your 100 contracts for $45 and take the profit early without waiting for the outcome.
Peer-to-Peer, Not Against the House
This is the single most important distinction between Kalshi and a traditional sportsbook. On a sportsbook, you bet against the operator, and the operator sets the odds with a built-in margin so the house profits over time. On Kalshi, you trade against other users. The price is set by supply and demand between buyers and sellers, not by a bookmaker. Kalshi itself does not take a position on which side wins; it runs the marketplace and collects a small transaction fee.
That structure has two practical effects. First, pricing tends to reflect real probability rather than a margin baked in to favor the operator. Second, because contracts settle at a fixed $1.00, your maximum gain and maximum loss on any position are both known before you enter the trade.
What You Can Trade on Kalshi
Kalshi lists thousands of contracts across a wide set of categories. The mix is far broader than sports alone, even though sports has become the largest driver of trading volume.
- Economics and finance: Federal Reserve rate decisions, inflation prints, jobs reports, and gross domestic product figures.
- Politics and elections: election winners, control of Congress, and policy outcomes, cleared for listing after federal court rulings in 2024.
- Weather and climate: daily temperature highs, hurricane landfalls, and snowfall totals for specific cities.
- Sports: game winners, championship outcomes, and tournament results, including markets tied to the 2026 FIFA World Cup.
- Culture and entertainment: award show results, box office numbers, and other pop-culture outcomes.
- Crypto and technology: price thresholds for major cryptocurrencies and milestones in the tech sector.
Kalshi vs Polymarket vs a Traditional Sportsbook
People often confuse Kalshi with Polymarket or with sports betting apps. They overlap in the idea of predicting outcomes, but the structure, regulation, and mechanics are different. The table below lays out the key contrasts.
| Feature | Kalshi | Polymarket | Traditional Sportsbook |
|---|---|---|---|
| Regulator | CFTC (US federal) | Historically offshore, crypto-native | State gaming commissions |
| You trade against | Other users (peer-to-peer) | Other users (peer-to-peer) | The house |
| Settlement value | $0.00 to $1.00 per contract | $0.00 to $1.00 (in stablecoin) | Fixed payout on the bet slip |
| Funding | Bank, debit, wire, crypto (USD) | Primarily crypto (USDC) | Bank, card, cash |
| Sell before event ends | Yes | Yes | Usually only via cash-out offers |
| Topic range | Economics, weather, politics, sports, culture | Broad, crypto-heavy audience | Mostly sports |
| US availability | Legal, federally regulated | Access varies by jurisdiction | Legal only in states that permit it |
The short version: Kalshi and Polymarket are both prediction markets where you trade against other people, while a sportsbook is a betting operator you play against. Kalshi’s defining feature is that it sits inside the US federal derivatives framework rather than a state gambling framework, which shapes almost everything about how it operates.
Is Kalshi Legit and Is It Legal?
Kalshi is a legitimate, regulated company, not an offshore operator. Its contracts are listed on a CFTC-designated contract market, customer funds are held in segregated accounts, and the platform must follow federal rules for how markets are created and settled. For a US resident, trading event contracts on Kalshi is legal at the federal level.
The nuance sits at the state level, and this is where the story has moved quickly. Two threads matter.
Election Markets
For years the CFTC resisted letting Kalshi list markets on US elections. That changed in 2024, when federal courts, including the DC Circuit, cleared Kalshi to offer contracts on election outcomes and control of Congress. Election and political markets have been live since.
Sports Event Contracts and the State Fight
Kalshi’s push into sports event contracts opened a larger legal battle. Several states argued that sports contracts look like sports betting and should require a state gambling license. Kalshi argued that its contracts are federally regulated swaps and that federal law overrides state gambling rules.
In April 2026, the US Court of Appeals for the Third Circuit became the first federal appeals court to side largely with Kalshi on this point. It affirmed a preliminary injunction blocking New Jersey from enforcing its gambling laws against Kalshi and held that the Commodity Exchange Act preempts state gambling law as applied to these contracts. That ruling was a major win, but it is one circuit, and the fight is not over.
Other states have gone the other way. A Massachusetts court found Kalshi’s sports contracts subject to state gaming law. Arizona and Michigan have pushed back through their own actions, and Minnesota moved to ban prediction markets outright. Litigation is ongoing across multiple states, and the question of who has final authority over sports event contracts may eventually reach the US Supreme Court. If you plan to trade sports markets specifically, check the current status in your state, because it can change on short notice.
How Much Does Kalshi Cost? Fees Explained
Kalshi does not charge a membership fee, and it does not charge a separate settlement fee when a contract resolves. The main cost is a per-contract trading fee, and it is structured in a way that many first-time users find counterintuitive.
The trading fee is probability-weighted. Rather than a flat percentage, the fee is largest on contracts priced near 50 cents (the most uncertain, coin-flip outcomes) and smallest on contracts priced near 1 cent or 99 cents (near-certain outcomes). In practice, the taker fee works out to roughly 7 cents multiplied by the price and by one minus the price, per contract. Maker orders (resting orders that add liquidity and only fill when someone trades against them) are charged at a fraction of the taker rate, around one quarter of it.
Here is what that means at a few price points, per contract:
- At 50 cents: the fee is at its peak, roughly 1.75 cents per contract. This is the most expensive point on the curve.
- At 10 cents or 90 cents: the fee drops sharply, to well under a penny per contract.
- Near 1 cent or 99 cents: the fee is a tiny fraction of a cent.
The design rewards conviction. The more confident the market is in an outcome (the closer the price sits to 0 or 100 cents), the less you pay to trade it. Because exact fee figures and any special-event fees can change, treat these numbers as the current structure rather than a permanent guarantee, and check Kalshi’s published fee schedule before trading serious size.
Funding, Withdrawals, and the Apps
Kalshi accounts are funded in US dollars, and the platform supports several deposit methods. Bank transfers by ACH carry no deposit fee and typically clear in one to three business days. Debit card deposits are near instant but usually carry a small processing fee, around 2 percent. Wire transfers suit larger amounts and generally have a higher minimum, in the range of $1,000. Kalshi also accepts stablecoin and crypto deposits, with USD Coin (USDC) converting one to one with the dollar, which appeals to traders who already hold crypto and want to skip bank delays. The general minimum deposit is around $10 for most methods.
Withdrawals follow the same rails, and Kalshi does not charge for standard ACH withdrawals. The company offers full-featured apps on both iOS and Android in addition to the web platform, so you can browse markets, place trades, and manage funds from a phone.
Why Kalshi Matters in 2026
Kalshi has moved from a niche experiment to the clear leader in US prediction markets. By 2026 the company had raised roughly $1 billion in a round that valued it at about $22 billion, with backing from major venture and institutional investors. Reporting through the year put Kalshi at the front of the category, accounting for the large majority of US prediction-market activity, as trading volumes climbed sharply on the back of election coverage, its role as a prediction-market partner for the 2026 FIFA World Cup, and rising interest from institutional traders.
There is a bigger idea behind the growth. Prediction markets produce a live, money-backed probability for questions that used to rely on polls, pundits, or guesswork. Because traders put real capital behind their views, the resulting prices can be a useful signal about everything from rate decisions to election outcomes. That is why economists, journalists, and analysts increasingly cite Kalshi prices the way they once cited betting odds or survey averages.
Risks and Things to Know Before You Trade
Kalshi is regulated, but it is not risk-free. Event contracts are speculative, and it is entirely possible to lose the money you put into a position. Prices can move fast around news, liquidity is thinner on obscure markets than on headline ones, and a contract that looks like a near-lock can still resolve against you.
A few practical points worth keeping in mind. Read the resolution rules for any market before you trade, because the exact wording determines how it settles and edge cases can surprise you. Understand that fees, while small, add up on high-frequency trading. And remember the state-by-state legal picture for sports markets is still shifting, so availability of specific contracts can vary depending on where you live. Approached with those caveats, Kalshi is a straightforward, transparent way to act on a view about the future inside a federally regulated venue.
Frequently Asked Questions
Is Kalshi legal in the United States?
Yes. Kalshi is a CFTC-regulated designated contract market, so trading event contracts on it is legal for US residents at the federal level. Election markets have been permitted since 2024 court rulings. The one area still being litigated is sports event contracts, where some states argue they need a gambling license. A federal appeals court sided largely with Kalshi in 2026, but a few states have restricted or contested certain markets, so check your state’s current status for sports contracts.
How does Kalshi make money if you trade against other users?
Kalshi does not take the other side of your trade the way a sportsbook does. Instead it runs the marketplace and earns a small per-contract trading fee. That fee is probability-weighted, meaning it is highest on coin-flip contracts near 50 cents and lowest on near-certain contracts near 1 or 99 cents. There is no membership fee and no separate settlement fee.
What is the difference between Kalshi and Polymarket?
Both are prediction markets where you trade against other users rather than a house, and both use contracts that settle between $0 and $1. The main differences are regulation and funding. Kalshi is regulated by the US CFTC and funded in US dollars through banks, cards, wires, or crypto. Polymarket grew as a crypto-native platform funded primarily in stablecoins, with access that varies by jurisdiction.
Can you lose money on Kalshi?
Yes. Event contracts are speculative. If you hold a contract to settlement and your side is wrong, it is worth $0.00 and you lose what you paid. Prices also move before settlement, so a position can drop in value if the news turns against it. Your maximum loss on any single contract is capped at its purchase price, since contracts cannot fall below zero.
How do you deposit money into Kalshi?
You can fund a Kalshi account by ACH bank transfer (no fee, one to three business days), debit card (near instant, small processing fee), wire transfer (higher minimum, suited to large amounts), or crypto such as USDC, which converts one to one with the US dollar. The general minimum deposit is around $10 for most methods. Deposits and trading are available on the web and through Kalshi’s iOS and Android apps.
